PROCESS FOR THE PREPARATION OF SUGAR IN THE FORM OF FINE CRYSTALS.

N0 Drawing.

To all whom it may concern:

Be it known that I, PAUL KusTNER, a citizen of the French Republic,residing at Lille, in the N 0rd Province of France, have invented a newand useful Process for the Preparation of Sugar in the Form of FineCrystals, of which the following is a specification.

This invention has reference to a process for the preparation of sugarin the form of fine crystals and its object is to prepare by mechanicalmeans the sugar in the form of flour known as Brazilian sugar or aradowhich is now produced by working up melted sugar rapidly while allowingit to cool. Hitherto so far as I am aware no one has succeeded inbringing about mechanically this phenomenon of crystallization in asatisfactory manner, and in Portugal and Brazil, the countries of originof this sugar, it is still produced by the workmen operating the pans byhand. I have found as the result of experiments that this crystallineformation can be brought about mechanically by causing melted sugarcontaining only a small percentage of water to flow in a thin layer onto a plate to which a rapid vibratory movement is imparted. In coolingupon the vibrating plate, the sugar crystallizes in the form of flour.My process enables this kind of sugar to be readily produced on a largescale. All that is necessary is to provide a sheet metal or like tableto which, in any known manner, a rapid vibratory movement is imparted,and to allow a thin layer of the melted sugar to flow on to the table.The process may be a continuous Copies of this patent may be obtainedfor five cents each, by addressing the Specification of Letters Patent.

one if the table be inclined slightly, or if an endless band be employedin place of table, or if the table be constructed on the princlple ofthe well known Kreiss jerking conveyer.

What I claim as my invention and desire to secure by Letters Patent isl. A process of producing sugar in the form of fine crystals or flour,consisting in causing melted sugar to flow on to an approximatelyhorizontal surface and imparting rapid vibratory motion in anapproximately horizontal plane to the said surface.

2. The process of producing Brazilian or arado sugar which consists incausing melted sugar containing only a small percentage of water to flowin a thin layer on to an approximately horizontal surface and impartingrapid vibratory movements in an approximately horizontal plane to thesaid surface while allowing the sugar to cool thereon.

3. A continuous process for the production of Brazilian sugar,consisting in causing melted sugar to flow in a thin layer on to anendless traveling band and imparting rapid longitudinal vibratorymovements to the said band while allowing the sugar to cool thereon.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
